* From state table to state diagram

I know there are already features in orgmode to create tables and to
generate images from text diagrams (via ditaa). It is also possible,
theoretically speaking, to convert from a state table representing a
state machine to a diagram. Does anything exist, either in orgmode or
externally, to do the latter (esp. to text diagrams)? I haven't been
able to find anything.

Check out graphic. I imagine it would be straightforward to integrate this via babel if it hasn't already been done.

Could you, or anyone else, perhaps elaborate, please? Searching for
"graphic" on google and so on is... pointless. Thanks.

I guess you mean org-babel rather than babel.el (an "interface to web
translation services such as Babelfish").

Okay, thanks. I know about graphviz, but it is not really what I am
looking for. Ideally I would create a state transition table and then
just "magically" get a diagram as a by-product. I can definitely see
that the DOT language might be a good target though - generating that
from a table should be easier than generating a diagram directly.

Well, maybe it's a bit specific and nobody has done anything so I should
look into it on my own :)

Yes, that is what I was thinking (but did not want to type on the
little on-screen keyboard of my phone...) when I suggested graphviz:
dot could be a good intermediate language.

It is indeed specific but I think there would be some interest in what
you manage to concoct so please post it here!

If I were to have time to do this right now, I would probably use awk
to convert a state transition table to a dot graph representation but
only because I'm very comfortable with awk and much less so with emacs
lisp...

And the ease will depend on the type of transition table you have as
the starting point, of course...

As an aside, when it comes to actually generating a diagram, I would
in practive typically use tikz due to the quality of the graphs that
can be achieved.  However, it may be harder to do a table \to tikz
translation automatically.

Babel does support generating diagrams with graphviz via "dot" code
blocks.  Babel is also capable of converting Org-mode tables to list
objects in a number of languages, so I'd recommend writing a table->dot
script in your favorite language, and then using babel to handle the
coordination and Org-mode integration.

I'm happy to help in this regard, the first step would be something like
the following example which assumes python is your preferred scripting
language (as you can see I have no idea what your state table may look
like)...

--8<---------------cut here---------------start------------->8---
#+results: state-table
| 1 | 2 |
| 3 | 4 |

#+source: table-to-dot
#+begin_src python :var table=state-table
python code here
#+end_src

#+begin_src dot :var text=table-to-dot(table=state-table)
graph{
$text } #+end_src --8<---------------cut here---------------end--------------->8--- Once this is working I think it could make a great addition to the library of babel [1] (a collection of generally useful code blocks).

Hi Gary,

The answer is that python receives that as [[1, 2], [3, 4]]. There are a
few ways to arrive at that answer. For your table-to-dot script I
suspect it is going to be easiest to use the ":results output" header
argument, which means that the result will be the printed output of the
python block (as opposed to...[1]). So using that, one way to see how

#+source: table-to-dot
#+begin_src python :var table=state-table :results output
print str(table)
#+end_src

#+results: table-to-dot
: [[1, 2], [3, 4]]

Another way is to place point in the code block and use C-c C-v C-v
org-babel-expand-src-block'.

Alternatively, you might want to use a session to play around with the
input data structure interactively. In that case, add ":session", and
use either C-u C-c C-v C-z or C-u C-c C-v z to bring up the emacs python
session with the input variable pre-loaded.

Gary,

One other request for you to entertain.  When you get into the Python
code (I can help with this, if you need it) think about organizing it
such  that you can use multiple output mechanisms.  For example, default
it to use dot as you have been talking about but allow for the use of
tikz as Erik Fraga mentioned in August.  This would imply converting to
some intermediate representation from the table form and then passing
that data to a dynamically selected back-end output engine.

I suggest tikz as an alternative since it can make such beautiful
graphs.

I haven't made use of babel yet so I don't know all its ins and outs
but I expect that there are ways of passing additional information to
the language doing the heavy lifting so we could add various output
modules...

Mark

I just started, in another context, to look into radio tables, and I thought
- wouldn't this be an option? I mean - putting a radio table into a plantuml
block and translating it, should not be to difficult? And it would be
perfectly in line with org. The same could be done for graphviz.

Just an idea,

Cheers,

Rainer

You first need to decide on a syntax:
how many cols in the table and what do they
mean.

A Confluence plugin does that. You may want to check it out for inspiration and
nice examples:

Dot is a really simple language, so translating to it should be easy. Eg
| state1 | state2 | transition |
becomes
state1 -> state2 [label="transition"]
